Acoustic Shell Optimization in Opera Houses for Concert Halls by Umberto Derme, Silvana Sukaj, Amelia Trematerra

“…Opera houses are often used as concert halls with the use of a temporary acoustic shell set on stage. In most cases, the shell shape and its position in the fly tower are decided by theatre technicians, after evaluating the concert programme and considering the conductor and the musicians’ requests, without being supported by an acoustic analysis. …”

Zinc Chalcogenide Based Shell Layers for Colloidal Quantum Wells by Cagatay Han Aldemir, Ahmet Faruk Yazici, Nehir Ergezer, Taha Can Korkmaz, Evren Mutlugun, Yusuf Kelestemur

“…Abstract Colloidal quantum wells, also known as colloidal nanoplatelets (NPLs), have emerged as a promising class of materials for light‐emitting devices (LEDs). However, the most widely studied core/shell NPLs, which rely on cadmium‐based shell layers, face challenges due to toxicity concerns and improper charge confinement. …”

Ni3S2@MoO3@Co3O4@AMO/NF core–shell heterostructure for high performance alkaline overall water splitting by Jiabang Liang, Yu Liu, Zegao Wang, Yifan Jia, Zhao Ding, Liangjuan Gao

“…Abstract The urgent need for bi-functional high-performance non-noble metal-based catalysts for water splitting requires the integration of both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) together, which not only increases the energy efficiency but also reduces fabrication cost. However, most non-noble metal-based catalysts for OER are not stable under alkaline conditions, while HER shows poor kinetic performance under alkaline conditions, which prevents the water splitting from scale-up applications. …”
